In both dramas, one or both of the leads time travel within a limited period of time, trying to change events in the present/near future that they don't have the full picture of. The ML's personality changes from what it is initially (from cheerful to withdrawn/somber in MDD and from selfish to self-sacrificing in TWY), and both FLs are sunshine personalities who bring light to the ML's life. Both couples have very good chemistry.

Both have uncles that love their nephew's girlfriend
Both have MLs that secretly help the FLs
Both have uncles that are considered as head of the family

Maid's revenge is darker in tone while Don't mess is very lighthearted.

Serial killers and more serial killers. Both dramas deal heavily with serial killers and the police attempting to catch them. The pacing is tighter in Aku no Hado, but Yuki Furukawa and Nattarat Nopparatayapon are equally proficient at playing super creepy dudes.

Both male leads have lost the women they love to violence and are on a bit of a revenge kick. Seigi no Tenbin is milder in content than Voice, and it does have a tighter script.

Both shows have in common:
The female lead personality is alike.
Both female leads are called "Tiger Moth" because they can't help seeking for justice when in front of injustice even when the situation is unfavorable for them.
The MLs personalities are not the same, but in both shows, the male leads think the FLs should maintain a low profile, but they can't help caring for them and helping in the end.
Workplace romance. In Law Cafe the leads are lawyer/prosecutor while in Into the Ring they are public servants.
I like the cute male leads who support female leads!!!

Bad Guys is about gangster and mafia characters, and Kei x Yaku has a Yakuza protagonist. Both are damn good; I'm actually a little obsessed with Kei x Yaku not gonna lie!

Bromance in this one is epic! Same mafia/gangster plot and characters. Even though Cruel city is more noir , I think it's worth a watch if you like bromance central violent plots

Right so Smoking has a bunch of not so good people working together with relationship drama and violent shit happening. Bad Guys Thai version is much darker and violent than the original k version which I love

Im loving just how much darker and violent Thai version of Bad Guys is and a show with bromance that comes close is Final Life. Violent, to the point where it's gross, and a bromance that is memorable.

Both have court room Drama.
Both shows have a procedural formula for Legal Cases with an overaching main plot.
Both shows have social commentary and they point out/deal with societal flaws and stereotypes.
Both shows are more focused on the courtroom stories and legal cases instead of romance.

Where it differs is that One Dollar Lawyer has sattire, eccentric lead and a more comedic tone while Miss Hammurabi has a more serious undertone centered on character development.

If you're interested in band music, you'll enjoy both Super Band and Great Seoul Invasion, where talented musicians and artists showcase their skills with various themed stage performances.

Galloped Era is a very good drama made with a pretty similar setup (locomotive production in the early era of Republic of China and lead by a stellar veteran cast (the actress who played Hua Fei in Zhenhuan Zhuan is the female lead). Highly recommended.

The main characters like the love interests but have difficulties in expressing their feelings for them....
They have the idol wall/shrine for them and admire them

both are sports dramas with comedy, romance and youth genres present. however, the main character of cheer up is female while racket boys has a male lead

Same crazy/cute atmosphere with a bit of gay panic, same self awareness and humour and a 80's vibe for the catchy opening song. I'm sure some of the team worked on both dramas or they are copycats, and I mean it as a compliment.
